Advanced 8-day course
Introduction to Smooth Manifolds and Observables
November 28 - December 8, 2006, Lublin, Poland
Lecturer: Giovanni Moreno


The course "Introduction to Smooth Manifolds and Observables" was intended as an introduction to the standard B1 course usually held at Diffiety Schools. No exercises were proposed to the students, and it covered the first half of the B1 program. Diplomas of participation were delivered to all the participants.
People who followed this course and are willing to discover more about Jet Nestruev might participate to some of the next editions of the Diffiety School, but they must be aware that the B1 course is wider and that several exercises are given.
